M26

The M26 grenade is a frag grenade that was the standard issue grenade of the US Military during the 1950s and 1960s, replacing the Mk II and preceding the M67. The M26 was first used in the Korean War after being developed to deal with complaints about the Mk II, such as its telltale smoke trail and its noise, and it was employed by the United States and its allies (specifically the United Kingdom, Brazil, Israel, Australia, Canada, Portugal) during wars in the 1950s and 1960s, seeing action in the Vietnam War after it replaced the Mk II. In 1968, the M67 replaced the M26 as the main grenade of the US Army.
